GAGE.

SPECIFICATION forming part of Letters Patent No. 660,176, dated October23, 1900.

Application a'led June 25, 1900. Serial No. 21,566. (No model.)

To all whom, it may concern:

Be it known that I, CHARLES F. WINsLow, a citizen of the United.States,residingat Pawtucket, in the county of Providence and State ofRhode Island, have invented new and useful Improvements in Gages, ofwhich the following is a specification.

This invention relates to new and useful improvements in gages; and itsprimary object is to provide a device of this character having anadjustable face whereby the same may be employed upon curved or unevenedges.

To these en ds the invention consists in providing a slotted bar withinwhich is slidably mounted a plate having a marking-pin secured thereto.This plate is provided with means whereby the same may be secured in adjusted position. A sleeve is slidably mounted upon the bar and isprovided with means whereby the same may be locked in adjusted position.A stud projects from one surface of the sleeve, and pivoted thereto arethe inner ends of two plates which form the face of Secured to eachplate is a slotted;

the gage. segment which is slidably mounted'upon a set-screw engagingthe sleeve. By this construction the sections of the face may be swungbackward or forward together or alternately and locked in such position,as will be hereinafter more fully described.

The invention also consists in certain novel features of constructionand combination of parts, as will be hereinafter fully described andclaimed, and illustratedin the accompanying drawings, showing thepreferred form of my invention, and in which,-

Figure 1 is a side elevation of the device. Fig. 2 is a top plan .viewthereof. Fig. 3 is a bottom plan view. Fig. 4 is an end view. Fig. 5 isacentral longitudinal section. Fig. Gis a bottom plan view showing indotted lines the portions of theface-plate in their various positions.

Referring to the figures of the drawings by numerals of reference, 1 isa gage-bar which is provided near one end with `a removable marking-pin2. A longitudinally-extending slot 3 is formed within the bar, and thisslot is countersunk at the lower edge thereof, as

'swing backward or forward thereon.

at 4, for the reception of a sliding plate 5. A marking-pin 6 is securedto this plate, and the sharpened end thereof projects from the lowerface. A bolt 7 extends upward from the plate and through the slot and isengaged by a thumb-nut 8, whereby the plate may be clamped in adjustedposition.

Slidably mounted upon the bar 1 is a sleeve 9ct' any desired form.Within this sleeve is mounted aset-screw 10,the inner end of which bearsupon a plate 11, which is adapted to be clamped upon the bar and holdsaid sleeve in adjusted position thereon.

Projecting from the lower face of the sleeve is a stud 12, which isadapted to receive a setscrew 13, which passes through slots 14, whichare formed within segments 15. These segments are secured to the outerends of two plates 16, said plates having looped ears 17 at their innerends, which are engaged by a bolt 18, secured to the lower face of thesleeve. This bolt serves as a pivot for the plates 16, and it is obviousthat the same are free to By this construction it will be seen that byloosening the set-screw 13 the segments 15 may be slid Vback or forthupon the said set-screw, carry ing the plates 16 therewith, and byturning the set-screw inward .the segments and their plates may besecurely clamped in adjusted position. It will be understood that thisconstruction of face-plate is especially adapted for use where it isdesired to describe a circle ywithin a circle or to describe a linewhich is parallel to a curved or uneven surface. The device is simple inconstruction and durable, and the face-plate may be set to any desiredinclination, asis obvious. are utilized in the construction of thedevice, it will be understood that the same may be cheaply manufactured.

In the foregoing description I have shown the preferred embodiment of myinvention; but I do not wish to be understood as limiting myselfthereto, as I am aware that modifications may be made therein withoutdeparting from the principle or sacricing any ofthe advantages thereof,and-I therefore reserve to myself the right to f make such changes asfairly fall within the scope of my invention.

As but few parts l Having thus described the invention, what is claimed,and desired to be secured by Letters Patent, is-

l.v The combination with a slotted bar; of a plate slidably mountedtherein and having a marking-pin secured thereto, means for locking theplate in'adjusted position, a sleeve upon the bar,a boltthereon,faceplates hinged to the bolt, and means for locking said platesupon the bolt.

2. The combination with a slotted bar; of a plate slidably mountedtherein, a markingpin secured to the plate, means for locking the platein adjusted position, an adjustable sleeve upon the bar, a boltprojecting from the sleeve, face-plates hinged to the bolt,

slotted segments to the face-plates, and means for binding said segmentsin adjusted position.

3. The combination with a slotted bar; of a plate slidably mountedWithin the slot, a marking-pin secured to the plate, means for lockingthe plate in adjusted position, an adjustable sleeve upon the'bar, abolt secured to the sleeve, face-plates hinged to the bolt at oppositesides thereof, slotted segments secured to the face-plates, and aset-screw within said slots and engaging the sleeve, said screw adaptedto lock the plates and segments in adjusted position.

4. The combination with a slotted bar hav ing a marking-pin therein; ofa plate slidably mounted Within the slot, a marking-pin secured to theplate, means for locking the plate in adjusted position, an adjustablesleeve upon the bar, a bolt secured to the sleeve, face-plates hinged tothe bolt at opposite sides thereof, slotted segments secured to theface-plates, and a set-screw Within said slots and engaging the sleeve,said serew adapted to lock the plates and segments in adjusted position.

5. The combination with a slotted bar having an adjustable marking-pinthereon; of a slidable sleeve upon the bar, hinged faceplates thereon,and means for locking the plates in adjusted position.

In testimony whereof I affix my signature in presence of two witnesses.
